Job Description

Hubstaff, a leading workforce analytics and time tracking platform serving over 95,000 businesses, is seeking a Senior Full Stack Engineer with Ruby on Rails expertise. This is a remote position perfect for an experienced developer looking for long-term growth with a product-led company that has been remote-first for over a decade.

The role offers an exciting opportunity to design and scale systems that power a high-performance, globally distributed SaaS platform. You'll be working with large datasets and high request volumes, implementing complex features using Ruby on Rails, and collaborating with an established engineering team. The position requires strong expertise in both backend development with Rails and modern frontend frameworks like React or Vue.js.

As a Senior Full Stack Engineer, you'll be more than just a feature builder – you'll be instrumental in shaping technical direction, improving architecture, and solving complex performance challenges. The role demands a deep understanding of scalable system design, database optimization, and modern architectural patterns. You'll work with technologies like Sidekiq, Redis, and PostgreSQL/MySQL, while maintaining high standards for code quality through automated testing and thorough code reviews.

The company offers competitive compensation ($95K-$105K), along with benefits including an annual retreat, home office budget, learning allowance, and PTO. Hubstaff values stability and deep product knowledge, making this an ideal position for engineers who want to grow with a product and team for years to come. Their remote-first culture emphasizes trust, autonomy, and asynchronous collaboration, providing an excellent environment for experienced developers who thrive in independent, high-impact roles.
